Abstract
A device (100) for controlling trapped ions (180) includes a first semiconductor substrate (120) comprising a semiconductor and/or dielectric material. A first micro-fabricated electrode structure (125) is disposed at a main side of the first substrate (120). The device (100) further includes a second substrate (140) comprising a semiconductor and/or dielectric material. A second micro-fabricated electrode structure (145) is disposed at a main side of the second substrate (140) opposite the main side of the first substrate (120). A plurality of spacer members (160) is disposed between the first substrate (120) and the second substrate (140). At least one ion trap is configured to trap ions (180) in a space between the first substrate (120) and the second substrate (140). The first micro-fabricated electrode structure (125) and the second micro-fabricated electrode structure (145) comprise electrodes of the ion trap. A multi-layer metal interconnect (135) is formed on the first substrate (120) and electrically connected to the first micro-fabricated electrode structure (125).
